The opposite of a diatonic harmony is chromatic. A chromatic scale is defined as:
a scale type that uses all 12 semitones.
Notice that the previous scale example had 8 notes. The chromatic scale uses all the sharp and
flat notes in between as well. There are 12 of each of the major, minor, etc. scales; there is only
one chromatic scale.
To illustrate a chromatic harmony, see the following example of a chromatic 3rd above harmony
on our C major scale.

The sharps show the non-scale notes. The reason for the difference is that the chromatic harmony
notes stay exactly 4 semitones (a major 3rd ) above each scale note. In the diatonic example, the
harmony notes varied between 3 and 4 semitones in order to stay true to the scale. The drawing
below demonstrates this.

The practical difference could be summed up in a couple of sentences:
Scale Harmony usually requires you to enter the one key that works for a whole song.
Scale harmonies will sound correct in many songs but not all and this is why you have a
choice between the two. Scale harmonies are also more active in harmony motion.
Chord Harmony requires you to input a different chord change for every chord in a
song. They can be applied to almost any song you can play.
This is only the practical difference between the two Harmony Control Modes, we now need to
explore the theoretical differences.
